Abstract
GeS2.5 chalcogenide glass was selected for studying effects of Ga addition on physical and structural properties. Glassy and partially crystallized samples of (100âx)GeS2.5âxGa (5 mol% ⤠x ⤠40 mol%) were prepared, and their thermal and optical properties were characterized. With increasing Ga content (x), values of Tg and optical band gap of glasses initially increased and then decreased, showing a maximal value at x = 25 mol%, that is, with stoichiometric composition of 85.7GeS2·14.3Ga2S3. These changes were discussed and correlated to evolution of network structure, which was investigated by Raman spectra recorded in glassy matrices of (100âx)GeS2.5âxGa (5 mol% ⤠x ⤠40 mol%). This work contributes to understanding of composition-structure-property relationship of chalcogenide glasses.
